20100004171 | Therapeutic Methods for Neuropathic Pain - The agrin protein was shown to be important in preventing the development of neuropathic pain, as well as in treating neuropathic pain. Both agrin protein and gene expression were shown to be down-regulated in mammals with neuropathic pain. Increasing either agrin gene expression or protein resulted in a decrease in the development of neuropathic pain. Agrin protein or the C-terminal agrin fragments can be administered in a number of ways, preferably by intrathecal injection. In addition, agrin can be increased by administering a compound shown to affect agrin gene expression or agrin protein concentration, e.g., SCP-I and SCP-M1 (also known as JMM). Agrin protein decrease was shown to be prevented by administering an NMDA receptor antagonist, e.g., MK801. Agrin and a C-terminal agrin fragment also induced phosphorylation of the NMDA receptor subunit NR1 at the serine residue site which led to suppression of neuropathic pain. | 01-07-2010 |
20100303887 | DHA and PEDF, a Therapeutic Composition for Nerve and Retinal Pigment Epithelial Cells - The combination of pigment epithelium-derived factor (PEDF) and docosahexaenoic acid (DHA) has been discovered to act synergistically to enhance cell survival and decrease apoptosis in retinal pigment epithelial (RPE) cells. PEDF and DHA synergistically protected RPE cells by confronted with oxidative stress by blocking apoptotic cell death and increasing the synthesis of the important mediator neuroprotectin D 1. Administering a composition comprising PEDF and DHA will halt or slow down the initiation and progression of macular degeneration, retinitis pigmentosa and retinal degeneration. In addition, the topical application of the combination of PEDF and DHA was found to promote cornea nerve regeneration after refractive surgery, and thus this combination could be used to prevent the complications of refractive surgery and certain diseases, e.g., neurotrophic keratitis due to Herpes virus. | 12-02-2010 |

20110009488 | Lipoxin A4 Protection for Cornea Endothelial Cells - Lipoxin A4 and its analogs have been discovered to promote the cell proliferation of cornea endothelial cells, and thus promote the proper functioning of the labile tissue layer of cornea endothelial cells. These lipoxin compounds can be administered alone or in combination with other known compounds as a solution that can be topically administered to decrease the swelling of the cornea or maintain the clarity of the cornea. Lipoxin A4 or its analogs can also be combined with other known nutritive compounds to form a solution for storage of a cornea prior to transplantation. | 01-13-2011 |
